We should just have a way to add tempering chances to an item with another currency I guess or they rework tempering.
They only added this to reflect Last Epoch’s 1.0 success launch only a month after it’s initial launch and the tempering system is an exact copy of the forging in Last Epoch… Only we get less chances to temper. items just should have a random tempering amount chance just like LE at this point if it’s going to be a direct copy paste.
